FIREPLACE-HEATER.

SPECIFICATION formingpart of Letters Patent No.518,862, dated April 24, 1894.

Application filed June 9,1393 Serial No. 477,086- (No model.)

To all whom it may concern:

Be it known that I, HORACE BASSETT Soo- VILLE, a citizen of the United States, residing at New Waterford, in the county of Oolurn biana, State of Ohio, have invented certainnew and useful Improvements in Fireplace- Heaters; and I do hereby declare the following to be a full, clear, and exact description of the lnvention, such as will enable others skllled in the art to which it appertains to make and use the same.

This invention relates to fire place heaters the heat out into the room by a'damper which cuts ofif escape up chimney, the back and sides belng constructed to retain the heat, with all openings entirely done away except those in front which act as a bellows to fan the fi-re.

Openings back of the tile not only crack and break tile by extreme heat one side and cold air the other side but the heat is lost, and the object sought is defeated by creating a cold air draft to carry off the very heat wanted up chlmney, hence, no opening should ever go back of tile, but the back should be solid to retain all heat produced which is reflected into the-room, if out off above, by damper.

The invention consists essentially-in the provision of a series of openings in the grate rest to correspond in position and'size with a corresponding series of air channels, or flutes, formed in the inner sides of the fire pot, back, and sldes, and in a damper for regulating the said openings in the grate rest, to control the supply of air through the air channels in the fire pot, back, and sides.

The invention further consists of the novel features, and the peculiar construction, andcombination of the parts, which will behereinafter more fully described, and claimed, and which are shown in the annexed drawings, in which Figure 1, is a perspective view of a heater constructed in accordance with, and embodying my invention, parts being broken away to show the details of construction, and the relative disposition of the parts. Fig. 2 is a horizontal section taken on a line just above the grate. Fig. 3 is adetailed section, show ing the means for adjusting the damper at the top of .the heater.

' The heater in its general construction presents the. appearance of a fire place heater of ordinary construction,and comprisesthe front -A, the grate B, the front grate O, the back and sides D and E, respectively, the inclined top F, the grate rest G, the ash pit H, formed in the usualmanner, and the ash pit door I.

The rocking shaker J 'is of ordinary construction and is journaled in suitable bearings to be conveniently rocked when it is desired to shake the fire, the latter operation being effected in the most convenient manner, preferably by a poker or other instrument which is adapted to be removably applied to a curved arm j, extending from the said shaker.

The grate rest G may be of any well known form of construction and is supported on the back and sides constituting the ash pit, and is provided with a series of openings, g, in

sition and size with the vertical channels, or

air passages, m, formed in the fire pot back, andsides, to permit of the free passage of the air to said channels or'passages from the lower endthereof, to the fire; thereby sustaining and promoting the combustion at the back and sides of the fire, and retaining the heat at the back, D, and the sides, E, E, at the proper temperature to obtain the best possible advantages in heating. A damper, N, is provided for regulating the size of the openings, g, to control the air in its passage to the channels, m. This damper N is composed of a back strip to close the series of openings in the back bar of the grate rest, and end strips, 02 to close the series of openings formed in the end bars of the said grate rest. These end strips, n, have notches in their inner edges to register with the openingsformed in the end bars of the grate rest, when the damper is operated: to open full, the series of open-ings in the back, and end bars of the grate rest. Obviously, as the damper is drawn out the openings in the back and end bars of the grate rest are closed so as to shut oi the supply of air. The damper is suitably supported by short bars, which form a part of, or, are attached to the grate rest, and is operated by a rod, n which projects forward beyond the front bar of the grate rest and passes through a keeper cast therewith. To operate the damper a poker or other instrument is applied thereto in the usual manner, the damper being operated by being pushed in, or drawn out.

The fire pot back, B, and the sides, E, E, are constructed of tiling; and are formed in their inner sides with a series of vertical channels m to form air passages. These channels or air passages, m, will be of sufficient size, and capacity, to furnish the proper amount of air to support the fire, and promote co1nbustion. The sides, E, E, flare outward, from their inner edges, and extend in a vertical direction. The top F inclines gradually from back to front, and terminates short of the grate front A to form a passage, f, for the escape of gases and dust. A damper, K, is provided to control and regulate the size of the passage fiand is hinged at its front end to the grate front A, and is free to rise and fall at its inner end. A notched lever or bar It, is pivotally connected with the damper K, and is adapted to engage with a keeper, 70' projected inward from the grate front A. The damper K, can be opened the proper degree and held in the required position by engaging the notch bar 70, with the said keeper 7a. The damper K, and the notch bar 70, can be operated by means of a poker or other convenient instrument, when it is desired to move the said damper, to vary the draft through passa e The ash pit door I is provided near each end with hooks h, which engage with lugs, a, on the grate front A, to hold the said door 1n place. This door is provided with a damper to control the draft through the ash pit, and is provided near its upper end with an opening through which the rod, n or the curve arm 3; the same, without removing the door, 1.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- p 1. In a fire place heater having vertical air passages in the back and sides leading from the ash pit, a single damper constructed to control the said back and side air passages located at the top of the ash pit immediately below the grate, substantially as described.

2. In a fire place heater, the combination with the back and the side tilings having vertical air passages in the inner sides, a grate rest having openings corresponding with the said air passages, and a single damper located on the under side of the grate rest to control the openings therethrough, substantially as set forth.

In testimony whereof I aiiix my signature 1n presence of two witnesses.
